[PATCH v3 08/14] media: platform: pxa_camera: make printk consistent

Robert Jarzmik
2016-08-08T19:31:27Z

Make all print consistent by always using :
- dev_xxx(pcdev_to_dev(pcdev), ....)

This prepares the soc_camera adherence removal by making these call rely
on only pcdev, and not the soc_camera icd structure.
